Industrial endoscope before use must be the necessary inspection and calibration work in the latter part of the inspection to improve accuracy, if used rashly, may bring unpredictable losses. Here to talk about the endoscope pre-calibration check
1, under adequate lighting to observe the external surface of the endoscope, should be smooth and smooth No scratches Burr plating surface should be uniform color, there should be no obvious scratches Flaws and visible cracks Pinhole Punctuation Burr paint or Spray the surface should be smooth, uniform color, there should be no bubbling peeling cracking phenomenon.
2, the light spot in the normal working distance at the measured end to place a whiteboard, with immersion light or endoscope with light source illumination, from the eyepiece or monitor with the naked eye to observe the illumination spot should be filled with the field of view, no obvious Bright and dark areas.
3, field diaphragm marking (for fiber endoscope) In the normal working distance, placed in the measured end of a whiteboard, immersion light or endoscope comes with lighting, looking through the eyepiece, the field of view Light bar arrow indicates the direction of the direction of the marker should be above.
4, degumming or mildew In the normal working distance at the measured end to place a whiteboard, with immersion light or endoscopic light source lighting, from the eyepiece or monitor with the naked eye to observe, there should be no obvious degumming Or mildew phenomenon.
